What 126 real products and emails actually do

We tagged every teardown in the library with the biases it uses and a verdict. This page counts them. It updates each time the library does.

Honest nudge, grey area or dark pattern?

60% of what we captured is an honest nudge with no conditions. 27% is honest only if something on the page is true, usually a deadline or a "was" price. 13% sits in a grey area. None is an outright dark pattern. That says more about what big brands put on their main pages than about the industry: the worst tricks tend to sit deeper in checkout and cancellation flows, which we have captured less of so far.

The biases brands lean on most

Counting every tag, primary and secondary. "Free" does a lot of work: the zero-price effect appears in 28 teardowns, even though the evidence behind it is mixed. 49% of all teardowns use at least one price tactic.

By surface

The mix changes with the page. Pricing pages lean on how the price is framed. Homepages lean on other people: reviews, logos and awards. Emails lean on time.
